Water Score for Multifamily Housing

Image of a decorative chart.

The EPA’s Water Score for multifamily buildings is generated by the ENERGY STAR® Portfolio Manager® tool and supported by WaterSense. The score is a 1 - 100 rating of how your building uses water compared to similar properties nationwide. If you are already tracking energy use in Portfolio Manager, getting your EPA Water Score is simple. All you need is a year of metered utility bills, so get your score and start saving!

Once you know your building’s score, use EPA’s tools and resources to find out how you can make changes or upgrades to save water, energy, and operating costs. What’s more, you can use your score to set your building apart from others in the market.
